A Case of Implant Denture used with Magnetic Force

Abstract

Since 10 years ago, I had continued to report the utility of the denture retainer applied the strong magnetic attraction between the ultra-minute Sm-Co magnet and the casting ferromagnetic alloys.
Here, I report the retainer of implant denture applied magnetic force, which I designed this time,and their good clinical results.
The main cause of failures of the implant denture was the effects of excess occlusal pressure against abutment implant.
Therefore, I designed the loose, not so close as traditional, connector of the abutment implant and denture applied the magnetic force, which devised the link to relieve the excess load.
It was proved that the implants were stiff and that the magnetic force could give adequate support and stability to the implant denture.
